HAT DIE.

Application filed March 8, 1922. Serial No. 542,020.

To all whom it may concern:

Be it known that I, Ismon KIWAD, citizen of the United States, residing at New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Hat Dies, of which the followin is a specification.

This invention re ates to hat making and forming machines and more particularly to a novel and improved method of shaping the material to produce what is known in the art as a bell crown, cushion brim hat.

The primary object of the invention resides in the construction of a hat shaping and forming machine designed to steam the material during the forming or shaping process, including provision for making uniform, various sized and shaped hats with rapidity and skill and with the minimum amount of hand labor.

One of the objects of my invention is the provision of a hat making and forming machine wherein the steam pot is designed to accommodate various sized and shaped dies, including means for forming a cushion brim hat of any desired width on diflerent shaped dies.

Another and still very important object of the invention is the provision of a hatforming 'and shaping device wherein the steam pot is designed to accommodate different dies so as to produce a hat presenting a natural edge, as is termed by those skilled in the art, which may take various shapes as the same is formed during the process.

With these and other objects in view the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the subject matter being claimed, it being understood that various changes in the form, proportion, size and minor details of construction may be resorted to without departing from the spirit and scope ofthe invention.

In the drawings: Figure 1 is a front elevation showing the steam pot and size former thereon and the plunger head in its raise position.

Figure 11 is a view showing the steam pot and size former in position and the head and ring lowered.

Figure 12 is a view of the hat when formed and removed from the steam pot.

Figure 13 is a modified form of the steam pot when used to produce what is known as a turban shaped hat with a natural ed Figure 14 is a plan view of the mo 1fied form and Figure 15 is an enlarged sectional view of a detail of the modified form of the invention.

Referring now to the drawings wherein like reference characters designate corresponding parts throughout the several views, 5 designates in its entirety the rigid frame or support of a conventional type of hat forming and hat making machine having a tablefi on which the steam pot and former is conveniently placed for the convenience of, the operator. The support 5 carries a pair of rods 7, 8 which are normally maintained in raised position by heavy resilient springs 9 and are adapted to be depressed hy the foot lever 10 wherehy a plunger carrying block may be moved over the ma terial to be formed. The above construction is well lmown in the hat making art and the invention primarily resides in utilizing this type at machine in the manner new to he set forth in detail,

@entrally disposed on the table 6 l have positioned a steam pot it]. provided apertured lugs 15 on the bottom 13 tlnzreoi whereby thumb screws 14 or other suitablealso provided with a similar clamp and slot fastening elements may securely maintain the same in position. The steam pot may be variousl made and in the form shown is provide with an annular head 15 having an inwardly extending flange 16 thereon, the side of the steam pot being curved inwardly from the head to the bottom 13 so that the bottom is somewhat; smaller in diameter than the head as clearly shown. The flange 16 is provided with a series of radial notches 17 whereby a die or shape may be placed on the flan e 16 and within the steam pot as clearly disclosed by Figures?) and The die 18 is provided with lugs or extensions 19 on its outer periphery to engage within the recesses 17 to securely position the said die within the steam pot. The depending portion of the die which shapes the materialv is of course open at the top and has formed therein a plurality of small apertures 20 to permit the steam to enter therein and steam the material before the same is formed into' a hat. Within the lower portion of the steam pot the conduit 21 and control valve 22 is arranged so that as the steam enters the pot the steam paddle 24 rotatable on the pin 25, secured to the bottom 13,-will drive the moisture to the inner side walls of the steam pot and when the moisture condenses, it may flow through an aperture 26 in the bottom thereof. An air line 28 also in the bottom of the steam pot permits of air to enter and cool the material.

Referrin in particular to Figures 3 and 5 it will be 0 served that the die is provided with what I term an insert or removable section 27, the outer periphery thereof being in the form of a segment and sitting in a recess formed in the flange 16 of the head of the steam pot. The inner ed e 29 of the insert or movable section extends substantially to the'diameter of the oval or elliptical die and of course conforms to the shape thereof wherein the insert is secured in its proper positioni It will thus be readily understood y those skilled in the art that since the bottom of the die is considerably larger than the open top thereof and the material is placed in the die and formed, in order to remove the same, the insert or removable section must be raised and removed from. the die proper so that the formed hat may be taken out without bending or creasing. When the material 30 is placed in the die the edges will extend over the top of the steam pot as shown by Figures 1 and 9 for instance. At.

this stage of the process in the -formation of the hat a wire loop or split ring 31 1S positioned over the material so that the samef L "lot an in the UV therein to properly engage and grip the ring when the material is turned over the same in the manner subsequently to be referred to. The adjustment of the respective clamps nec essarily permits of formin the brim of the hat in different widths, t e inner edge of each clamping member being necessarily rounded or slightly curved as shown at 37 to roperly engage the split ring 31.

eference being had to Figures 7, 10 and 11 of the drawing, after the rin is positioned on the material, the size ormer or hollow cylindrical member 38 having a flange 39 thereon and a slightly offset enlarged bottom 40 is constructed so as to be placed into the die 18, the flange thus supporting the size former in position, it of course being understood that the open bottom of the size former permits of the insertion of a rubber sack 41 which may be partly filled with water by removing the top plug 42 therefrom. If so desired the sack may be inserted before the size former is placed over the die previous to operating the plunger hereinafter to be referred to. Referring to the various figures of the drawing it will be noted that the top edge of the size former is provided with a plurality of pins 43 so that as the material is drawn over the same and secured in the manner shown more in detail by Figure 10 the stretchin or forming operation on the material may 5181! take place since it will be observed that the varipps clamps also maintain and secure the material with the split ring.

"After the material is so positioned and drawn over the pins of the size former the operator is then ready to depress the foot lever so as to actuate and bring the rods 7 and 8 downwardly. Secured to the respective rods 7 and 8above referred to, there is provided a cross bar 44 which supports a substantially rectangular block 45. The cross bar 44 is slotted to receive the upper ends of the ring supporting rods 46 and attached to the cross bar 44 and preferably at right angles thereto a cross piece 47 is also provided and slotted at each end to receive the upper ends of a second pair of rin supporting rods 47, the lower ends of t e respective supporting rods 46 and 47 carry the wide ring 48 and by reason of the slotted portions of the respective rod 44 and cross piece 47 the radial adjustment of the ring 48 is provided for. The block 45 carries a standard 49, the bearing 50 at the upper end of said standard pivotally supporting the lever 51 which lever is provided with an oileet portion 52 and secured to the bifurcated end 53 Or a lifting red 54. The opposite bi- :iurcated end 55 of the lifting rod is at- .,e plunger red 56 passing through e lly of the block 45, the (3% carrying the plunger 08 as clearly shown by Figure 2 of the drawing. The outer end of the lever 51 is connected bya coil spring 57 attached to the block 45 and normally maintains the lever in the raised position.

It will of course, be readily understood that when the foot lever 10 is depressed the cross bar 44 carrying the ring 48 and the plunger operating mechanism above referred til . a at. epens tiltsto lowers the same over the material held between the clamps and the pins on the top of the size former and as the operator holds the ring 48 on the material and actuates the lever 51 the plunger may descend through the size former and engage the rubber sack placed within the die 18 consequently stretching and expanding the material to conform to the shape of the die in which it is laced.

he offset portion 40 of the size former being slightly larger in diameter than the upper end thereof forms the shape sov that the top edge 60 of the cushion brim 61 may be folded over as at 62 to the dotted line position. If so desired before the folding operation takes place an annular strip of rubber of any desired thickness may be placed over the size former and beneath the material so that the cushion brim when formed can be of different thickness if so desired. The split rubber ring may be subsequently removed from between the top and bottom 63, 64 of the brim as is well understood. After the plunging operation takes place and the material has been formed into the sha e as shown by Figure 12 the top edge of t e material is of course cut away below the pins along the dotted line as shown by Figure 11 so that when the portion 60 is bent inwardly the same will be substantially of the same width as the sweat band of the formed hat.

The width of the cushion brim as shown in the form, see Figure 12 may bemade in various widths as desired and by simply adjusting the clamps inwardly or outwardly on the die as well as the clamp 33 on the insert. Moreover the oval shaped die former must necessarily be of the desired size and shape. Attention is directed to the fact that when the foot lever is depressed and the ring 48 lowered over the material stretching the same to form the cushion brim that this operation. takes place simultaneously within. the die proper thus distending and pressing the same outwardly to the curved inner portion of the die. readily understood that since the partly filled such 41 is placed in the material, as the plunger 5' ends through the size former and into the l... the pressure exerted on the sack will lorce the eutwardly and thus con'ferni tn the ef the die 18. Be- :ietre In ml is shaped operator 9 and theroughly steams lwf It will be then the material thus permitting of its stretching and thus lends itself to the proper shaping as is well known in this art. The steam paddle, of course, tends to throw the moisture to the inner side of the steam pot and the operator may also open the valve 21 in the an line 28 to cool the form before the same is to be removed from the die and the operation repeated on the next hat.

In the modified form of the invention illustrated by Figures 13, 14 and 15 wherein I desire to form and shape the cloth to produce what is known as a turban shape with a natural edge, the same general arrangement is provided wherein the steam pot 11 receives a different shaped die 18, but, as shown the insert may be dispensed with. The dependin portion 19 in this form of die is practical y the same as that heretofore described and the upper edge terminates in a seat 20 for receiving an edge forming ring 21", the width of said ring being substantially of the same width and height of the seat as clearly shown by Figure 15 of the drawing. It will be observed that the ring 21' is bevelled at its respective corners so as to give and produce a natural. edge to the'rim of the hat when the same is formed. In this form of the inventionthe supporting rods 46 are threaded in the bushings 47 formed with the ring 48, the latter being substantially L-shaped in cross section so that the depending portion 49 may depress and force the ring inwardly to engage within the seat above referred to. In this form of the invention after the material is placed within the crown of the die 18 the ring 21 is inserted in the seat and the material 30 is drawn over the bevelled edges of the ring and folded over and inwardly thereon. The sack 41" of course is placed in the material before the plunger 58 is actuated so that the sack when distorted will force the material to the inner wall of the, die as is shown by Figure 13 of the drawing. It will thus be seen that the ring 48 will produce a natural rounded edge instead of a fiat brim and since the ring 21 may be subse uently removed, the same leaves an evelihy formed rolled natural edge finish to the hat as de sired.

While I have illustrated and described my invention with some degree of particularity,

I realize that in practice various alterations.

therein may be made. I therefore reserve the right and privilege of changing the form of the details of construction or otherwise altering the arrangement of the correlated parts without departing from the spirit of the invention or the scope of the appended claims.
